“…The ZnO nanostructures grown by this method are doped by only a few percent of copper and iron as the details are discussed in [45]. The photoluminescence from ZnO:Cu can generally be similar to pure ZnO nanostructures underlying physical mechanisms as free and defectbound excitons, deep and shallow donor-acceptor pair recombinations, and deep-defect associated emissions.…”

“…3,4 Chemical, mechanical, and thermal stability, 5 strong oxygen adsorption, 6 and low temperature growth 7 conditions of zinc oxide have made it an interesting material for use in different applications. In addition, owing to high sensitivity of zinc oxide to ultraviolet (UV) radiation it can be employed in fabricating UV photo-detectors with different applications, namely, environmental monitoring systems, space research, and optical communication.…”

Zinc oxide films were prepared using oblique angle deposition of Zn at four deposition angles of 0°, 30°, 45°, and 60°and subsequent annealing with the flow of oxygen. Structural characteristics of the films were obtained using atomic force microscopy and field emission scanning electron microscopy while their crystallography was investigated by x-ray diffraction analysis. The largest value of void fraction and the highest preferred orientation were obtained for the ZnO(101) diffraction line for the Zn film deposited at 45°. The former is explained in the published literature on the basis of rearrangement of atoms resulting from the diffusion or thermal vibration and the available crystallographic sites and surface energy on the substrate/growing film surface for relaxation of an adatom. Zn film anisotropy due to the bundling effect resulting from oblique angle deposition was examined by sheet resistivity measurements along x and y directions of the samples. Optical spectra of the samples were measured using both polarized light and unpolarized light from which optical constants were deduced. Both direct and indirect band gap energies were obtained and compared with the reported theoretical calculations. Our results are consistent with the experimental data in the literature; while they are larger than the theoretical reported values.
